Performance Evaluation of a Power Management Scheme for Disruption Tolerant Network

A Multi-Radio Power Mangement Scheme for Disruption Tolerant Networks

Power management for nodes in a sensor network is a topic of great interest due to the limited resources available on sensor devices and the need to maximize the network lifetime and delivery ratios. This problem is further compounded in Disruption Tolerant Networks (DTNs) since they are characterized with frequent partitions and intermittent connectivity, which may further suffer if the case o...

Power Management in Disruption Tolerant Networks

Performance evaluation of node density-based adaptive routing scheme for disruption tolerant networks

Traditional ad hoc routing protocols do not work in intermittently connected networks since end-to-end paths may not exist in such networks. Hence, routing mechanisms that can withstand disruptions need to be designed. A store-and-forward approach has been proposed for delivering messages in disruption tolerant networks. Recently, several approaches have been proposed for unicast routing in dis...

Advanced Data Access Scheme in Disruption Tolerant Network

Disruptiontolerant network (DTN) technologies are considered to be the successful solutions, allow nodes to communicate with each other in the extreme networking environments. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policy updating for secure data retrieval. The concept of attribute-based encryption (ABE) is a promising approach...

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
